It looks like a time out issue..

The controlling parameter is in the /tcb/files/auth/system/default file, towards the end "t_login_timeout#10:"
Change the #10 to a higher number or to #0 to completely disable it.

Once root account Locked,

You need to have Direct Console acces Login
to enable it,

# /usr/lbin/modprpw -k root
(above command will enable root account)

other tricky ways,

Considering you have "rcp"&rlogin" enabled
to try rlogin or rcp the passwd,

Thanks,

Hi

reboot your server interrupt the boot sequence when it says you have 10 seconds to do so, boot from the primary boot device, answer Y to interact with IPL, then boot into single user mode by doing hpux -is This will boot and log you in as root without a password, then you can reset the password and reboot back to normal

Thanks You..

Another avenue to the solution is to use sudo (if it is installed) to execute the "/usr/lbin/modprprw -k root" command as an administrative user with appropriate priveledges under sudo.

Even more useful, get used to doing system admin tasks requiring root access via sudo. This has two advantages:

1. You don't have to login as root and risk doing the unexpected as root if you have forgotten where you are or which system the window is connected to.

2. sudo produces a convenient log file to track what you were doing for review and documentation of your actions.
